3 way wiring

This post should be in the Electrical forum to receive the appropriate attention.

The only situation that I know of where you can run 2 conductors is for the travelers between switches. You still have to feed one switch hot and the other switch would provide the conductor going to the light. The light would still need a neutral and a ground. I don't see any savings one way or the other unless the switches were a long distance from one another.
